Trump's 12-day journey across Asia will not offer much of an escape as he travels to a region shadowed by the threat of a nuclear-capable North Korea.

Asked if Trump will use the heated "fire and fury" language he has used in the past when discussing North Korea while on the Asia trip, McMaster says, "the President will use whatever language he wants to use."

McMaster, Secretary of State Rex Tillerson and other top officials have met with Trump in recent days to prepare him for the upcoming trip.

Advisers have been attempting to focus Trump on the five country tour in recent weeks during briefing sessions aimed at avoiding diplomatic faux pas and other hiccups, according to reports.

Regardless of his language, Trump will be focused on curtailing the military threats coming out of Pyongyang and improving trade among other countries in the area, according to McMaster.

"President Trump will reiterate the plain fact that North Korea threatens not just our allies ... North Korea is a threat to the entire world," McMaster said during a White House press briefing Thursday. "So all nations of the world must do more to counter that threat. That is happening. But the President recognizes that we're running out of time and will ask all nations to do more."
